After laser treatment of rosacea, the capillaries in rosacea will expand in the early stage of 10 ~ 15 days. The hemoglobin inside will rupture the blood vessels after absorbing light, which will turn into light spots and produce purpura, which still looks red. The process of absorption is generally about two weeks, and there is even individual specificity. It's been three months, and the blood vessels in the whole face will be slowly absorbed.
